This request was evaluated by Red Hat Product Management for inclusion in a Red
Hat Enterprise Linux maintenance release. Product Management has requested
further review of this request by Red Hat Engineering, for potential
inclusion in a Red Hat Enterprise Linux Update release for currently deployed
products. This request is not yet committed for inclusion in an Update
release.

In order to debug this problem, we need the test case for RHEL 5.2 with an exact
reproducer, including output with verbose debugging messages from the DHCPV6
software. One way to do this would be to extract the commands that TAHI runs.
The man pages for dhcp6s, dhcp6r, and dhcp6c all show how to generate verbose
debug messages.
